1 GIS After the Conversion Mid West ESRI Utility Users Group 2007

2 Presented by: A Jeffrey A. Grussing Leader, GIS Development jgrussing@usgweb.com

3 Background Kandiyohi Power Cooperative Worked two years on their GIS system and field verification. United Services Group (USG) I have been with USG for 14 years where I have worked with several different cooperatives and municipals on GIS and field collection projects. I am currently the Leader of GIS development for USG.

4 The conversion is done, now what do I do? GPS field inventory to make your data more accurate both the attributes and positional Pros and Cons. Explore using GIS for corridor and ROW management, new route planning and storing easement data. Using the GIS system to manage and store PCB and pole testing data. Using GIS systems in conjunction with trouble call system, truck tracking, automated staking and CIS applications. Other uses for GIS - the sky is the limit.

5 GPS Field Inventory Pros Data is positionally accurate With a complete system inventory Accurate system worth Know where all foreign attachments are You can do retirement staking from the data Helps crews know what was there in a storm damage restoration It is a good way to field verify that everything came across from the conversion For Cooperatives, RUS will fund 75% of the project.

6 GPS Vs. Existing Mapping Data

7 GPS Field Inventory Cons Spatial Mismatch/Map Matching Problems Accurate GIS base map with less accurate GPS points. Accurate GPS data placed into a less accurate GIS base map. Accurate GPS data placed into a GIS base map that has a scale too small to differentiate the GPS points. Costly GPS equipment Work expenses: Data collection Integration into GIS system GIS clean-up Maintenance

8 GPS Field Inventory Cons? Visual representation Actual location may hinder ability to interpret map

9 GIS for ROW Clearing Right of way clearing data can be attached to parcels of land in the GIS. Keep track of areas that were trimmed or sprayed in a particular year. Attach digital photos of existing vegetation encroachments to parcels in the GIS. Clearing contractors can be given area maps generated from GIS data.

10 Example of ROW Clearing Database ROW Clearing Data in the GIS System Database

11 Example of Using Digital Photos Place Tree Symbols to Identify Problem Areas Display Hyperlink Photos of Problem Areas Attached Tree Symbols

12 Example of Contractors Service Territory Maps

13 Detail Printed Maps for Contractors

14 Using the GIS System for Storing Easement Information Storing the easement information in the GIS database. Storing the easement information in an external database or Land Information Systems (LIS). Attach scanned easement documents to parcels in the GIS system.

15 Example of Easement Database Transmission Line Easement Parcel Easement Data Stored in the GIS Database

16 Example of Hyperlinked Easement Transmission Line Easement Parcel Display a Hyperlink Scanned Easement

17 Using GIS for Route Planning Developing or acquiring parcel information. Creating proposed route centerline. Create and store alternative routes. Generating a contact list using the final proposed route centerline. Use in conjunction with automated staking software and or easement generation software.

18 Developing or Acquiring Easement Parcels Get Digital Parcel Data from Counties. Make sure that it is usable data Digitize or COGO Parcels from Paper Records. Use GPS and Automated Staking or Easement Generation Software.

19 Example of Defining Proposed Routes Alternative # 3 Alternative # 2 Alternative # 1

20 Example of Generating a Mailing List Generate Mailing List Report from Selected Parcels Select Proposed Route Select Parcels that Intersect Proposed Route

21 Example of Staking/Easement Software The Easement Parcel is Generated Starting Waypoint Additional Waypoints Ending Waypoint Known Monument (Section Corner)

22 Example of Staking/Easement Software

23 PCB and Pole Testing Data PCB test data for transformers and other primary equipment Produce maps that highlight equipment the needs to be changed out Store test data in related tables in the GIS database Pole testing and change out programs Produce maps that highlight pole change out areas and symbolize danger pole so you can dispatch crews to the worst pole first Store Pole test data in a related table in the GIS

25 Creating Ties to Other Systems Ties to CIS Real time, Near real time, import export and MultiSpeak. Ties to AVL or truck tracking systems For safety and ease of dispatching crews. Ties to Outage Management and Trouble call systems Using Automated Staking systems to maintain the GIS data

27 Example of a Trouble Call In this case this Fuse is probable cause of the outage Customer #3 Customer #2 Customer #1

28 Other Uses for GIS Great River Energy is using GIS to track failures in heat shield tiles in combustion turbines. Building cable management. Model substations. Model padmounted switchgear. Anything that has a spatial component and data behind it can be a candidate for GIS.
